MAGAZINE FIRE-ARM.

SPECIFICATION forming part-of Letters Patent No. 393.406, dated November 27, 1888.

Application filed May 18, 188B. Serial No. 274,342. (No model.)

To all whom it may concern:

'Be it known that we, FRrrz voN STEPsKr and ERICH STERZINGER, both of Trieste,in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Magazine Fire-Arms; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention relates to that class of breechloading and magazine fire-arms in which the breech-block slides backward and is operated by a lever, and particularly to that class in which the breech-block consists of a longitudinally-reciprocating bolt or plug.

The invention is particularly described in the following specification, and illustrated in the accompanying drawings, in which Figure l is a longitudinal vertical sectional view of the working parts of a gun embodying our improvements. Fig. 2 is a longitudinal vertical sectional view of the breech-bolt and the hammer and tiring-pin. Fig. 3 is a longitudinal horizontal sectionall view ofthe lockplate and magazine-box. Fig. -1 is a longitudinal vertical sectional view of the same. Fig. 5 'is a detail perspective view of one of the slide-blocks. Fig. 6 is a detail perspective view of the forked lever for operating the breech-bolt. Fig. 7 is a longitudinal horizontal sectional view of a portion of the lock-plate and the breech-bolt and hammer. Fig. 8 is a view of the inner side of the plate which forms the cover of the magazine-box, and Fig. 82l is a longitudinal sectional view ofthe same. Fig. 9 is a transverse vertical sectional View of a portion of the stock and magazine-box. Figs. l0 to 16, inclusive, are detail views, hereinafter more particularly referred to.

The lever mechanism for operating the breech-bolt is represented by the letters A B C. The part A B is' a lever of the first kind, having its fulcrum at a fixed point, ax, in the lower part of the lock plate or casing Ax. The stock Ax2 is secured to the casing by a bolt passing through it and through the rear eX- tensions,R and m,and the barrel BX2 is screwed into the front end of the casing. The lever A B is operated by the trigger-guard G,the front end of which is pivoted at bX to the end of the arm Bof thelever. The near end ofthe triggerguard C is arranged to slide in a slot, k, of the extension R, and is provided with a T-head, r, to prevent downward displacement.

The arm A of the lever is di-vided into two branches, and each branch is again divided or forked, as shown in perspective in Fig. 6. rIhese forked branches engage with studs t' on two connecting links or bars, D, the form of which is shown in perspective in Fig. 5.

rlhe links or bars D are connected by pivots d to the sides of the breech-bolt K, which slides in ways w in the casing Ax. The triggerguard Gis provided about midway of its length with a hole, c, for the reception of the linger of the operator. To operate the lever mechanism, the t rigger-gnard C is grasped by the thumb and lingers, with the second finger in the hole c, and the iirst finger lying about parallel with the length of the trigger-guard. The parts being in the position shown in full lines in Fig. l, the forward movement of the triggerguard throws the forked end of the lever` A backward to the position shown in dotted lines, and by the connection of the lever with the links or bars D the breech-bolt K is moved backward and the breech is opened to permit of the ejection of the empty shell and the insertion of a fresh cartridge.

The hammer and iiringpin consists of a spindle, H, working longitudinally in a cylindrical recess in the breech-bolt K. The front end of the spindleforms the firing-pin 7Lx,which works in a seat in the front end of the bolt K. About midway of the length of the spindle is a collar, o, which forms the abutment for one end of a spring, h, surrounding the spindle, the other abutment of which is formed by a plate or cap which closes the rear end of the cylindrical recess and is secured by a screw, 7c".

The rear end of the spindle H projects through the center of the plate or cap and is provided with a milled or roughened thumbpiece, H', by means of which the spindle may be drawn backward by the thumb and finger independently of the lever mechanism. When the spindle is thus independently drawn back, the links or bars D drop of their own gravity and work in recesses Z in the sides ofthe casing Ax, with the studs i working loosely in -the forks of the levers A, so that said devices 'do not interfere with each other.

On the under side of the spindle H, between IOO the 'collar 0 and the front end, is a longitudinal rib from which project downward two fins, L

N, for engagement with the sear. The tin N is hooked or projecting toward the front, and

constitutes the halt' cock notch, and the lin L forms a right angle at its front end and constitutes the full cock notch or shoulder for engagement with the scar.

The trigger G is pivoted at the pointg in to the lock plate or casing AX. The cam 'faced upper edge of the trigger engages with the long arnrof a bent lever, F, which has its fulcruni in the post E, and has its short arm pivoted to the lower end ofthe scar E. The upper end of the sear E is hooked rearward for engagement with the half-cock notch or hook N, and is of course equally adapted for engagement with the full-cock notch or shoulder L in the usual way. Vhen the scar is engaged ze with the half cock notch N, it is impossible t0 explode the cartridge, either accidentally or otherwise, because of the engagement of the hooked portions of the sear and the flu; but

when engaged with the full-cock notch or lin L the hammer and ringpin can be released by pulling the trigger.

The sear is pressed upward by the spring E', which holds it always in position for engagement with the half-cock and full-cock tins.

The extractorconsists of a V-shaped spring, M, arranged in a recess in the front portion of the breech-bolt K, with its lower arm projecting beyond the front end and formed with a hook, a, for engagement with the flange of the cartridge-head.

The operation of the' parts above described is as follows: When the trigger-guard C is moved forward, the forked lever A,by its engageinent with the links or bars D, as above 4o described, forces the breech-bolt K backward until said lever is in the position shown in dotted lines, during which movement the hook a of the extractor l\f[,`by its engagement with the rim of the cartridge-shell, withdraws said shell from the chamber of the breech and earries it backward until the breechbolt has reached the limit of its backward movement, when the front end or point of the firing-pin hX strikes the heel ol' the shell and ejects it 5o .through an opening in thccasing in the usual and Well-known manner. This operation is the same in all cases, whether the gun is used as a magazine or as a single-loader. When the gun is to be used as a magazinearm, the

magazine is secured in place in the position shown in Figs. l. and 9. gie-loader, the magazine is removed and a plate inserted in its place, as hereinafter more particularly described. The magazine T is 6o Carried by the magazine-box T2, which is suspended from the under side of the lock plate or casing A", as shown in Figs. l and 9, and is heldin place by screws or other suitable means, so that it Vcan be readily removed when desired.

" A' In the` bottom of the magazine T rests the carrier, which consists of a plate w, (see Fig.

When used as a sin- 14,) bent longitmlinally and having an upd ward curve toward the Frontend to correspond with the general form ot' the cartridges, and so that said cartridges may lie in alternately higher and lower planes and partially overlap each other, as shown in Figs. l and 12. To the under side ofthe rear end ol the carrier mis attached a box or barrel, a', which surrounds a helical spring, n, the lower end of which bears against the bottom of the magazine and the upper end bears against the bottom ofthe carrier iu order to raise it to feed the cartridges to the chamber of the barrel.

On one side of the magazine-box T'l is a casing or enlargement, t2, in which works a lever, m,pivoted in lugs m2, and having at the upper end a hook or catch, s, and at the lower end a button or stud, l, which projects through a hole slightly beyond the outer surface of the easing. Inside of the casing is a spring, m, which bears against the upper end of thelever and presses it inward, so as to cause the hook or catch s to engage with ratchet-teeth n and a on the side ofthe magazine T. Vhen the gun is used as a magazine-arm. thehook or catch s is engaged with the tooth u, so that the top of the magazine T is below the level of the ways w, as shown in Fig. 9, and when the breechbolt K is thrown back to open the breech the cartridges are free to rise when pressed upward by the carrier-spring n, so that by the forward movement of the breechbolt a cartridge may be inserted in the chamber of the breech.

W'hen the magazine is to be removed, in order to refill it or for any other purpose, by pressing on the button the catch s is disengaged from the tooth u, so that the magazine maybe raised, by the upward pressure of the spring o, to such a posit-ion that it may be lifted out of the magazine-box through the open breech.

Vhen the gun is to be used as a single-loader, the feedingplatc l (shown in Figs. 8 and 8) is inserted in the open breech above the magazine-box, and may be secured in place by means of screws passed through lugs at its ends or in any other suitable manner. The plate Plis of skeleton form, and has suspended below it a bowl, P', the top of whichcorrespends with the level of the chamber of the breech suficiently near to allow a cartridge placed in said bowl to be inserted in the charn- IOO IIO

ber of the breech by the forward movement of the breech-bolt K, as above described.

When the gun is to be used only as a singleloader, the magazine may be entirely removed and may be carried separately from the gun, and, if desired. it may be charged with cartridges, so as to be ready for immediate use when inserted in place.

Vhen the magazine is charged and in place in the magazine-boX,if it is desired to hold the magazine in reserve and use the gun as a single-loader, the magazine is pressed downward in the magazine-box (see Fig. 9) until the hook or catch s engages with the uppermost ratchet-tooth, a, by which means provision is made for the reception of the feeding-plate P2 and its bowl P, so that the cartridges may be fed singly to the chamber of the breech Without interfering with the operation ofthe magazine.

What we claim as new, and desire to secure by Letters Patent, is-

l. In a repeating rearm, the combination of the lever mechanism consisting of the dou! bleforkedlever A B and the trigger-guard C, having its front end pivoted to said lever and its rear end provided with a T-head and sliding in a slot of the extension R, with the links or barsD, provided with studs 't' and pivots d, and the rectilineally-sliding breech-bolt K, said links or bars D engaging the breech-bolt K and the forked lever A, respectively, by means of the pivots d and studs i, for opening and closing the breech, substantially as shown and described.

2. The magazinebox T2, provided with the casing t2 on one side inclo'sing the spring m and lever s t, and carrying the carrier-spring n2 and magazine-spring v, in combination with the magazine and carrier, substantially as herein described.

3. The magazine T, provided with the teeth a and u, in combination with the magazine-box T2, provided with the spring m and lever s t, and carrying the magazine-spring c, whereby provision is made for holding the magazine in place in the magazine-box and for removing it when desired, substantially as herein described.

4. The combination, with the magazine T, of the carrier x, consisting of a plate bent longitudinally and having an upward curve toward the front end to correspond with the general form of the cartridges, and of a width sufcient to hold a layer of cartridges side by side, with a number of layers of cartridges above the lowest layer all arranged to lie in alternately higher and lower planes and partially overlap each other, said carrier being provided with the box or barrel n', inelosing the spring n2, substantially as and for the purpose herein described.

5. The combination, with the magazine T and magazine-box T2, of the coiled spring n2, inclosed in the box or barrel u,and having its ends bearing respectively against the bottom of the magazine and the bottom of the carrier, and the coiled spring o, having its ends bearing respectively against the bottom of the magazine and the bottom of the magazine-box, substantially as and for the purpose herein described.

6. The combination, with the hooked tin or half-cock notch N,of the trigger G, pivoted at g, the elbow-lever F,having its fnlcrum in the post E, and having its long arm engaged by the cam-faced upper edge of the trigger, and the hooked scar E, pivoted to the short arm of the lever F and pressed upward by the spring E', all arranged and operating as herein shown and described.

In witness whereof Wehereunto set our hands in presence of two witnesses.
